NOTES ON NEW CABINET WOODS FROl\1 BRAZIL By KARL SCHMIEC 1 The making of fine furniture calls for not only the best of the standard cabinet woods of the trade, but also a great many of the rarer and lesser known kinds. In the whole course of our manufacture we use about one hundred different kinds of wood, emanating from all parts of the world. Brazil's ' ' contributions in the past have been few, notably Rosewood, Tulipwood, Kingwood, and Pernambuco \\'ood, but these have been long and favorably known. More recently other woods from that country have become available to cabinet makers and some of these are very promising. Following is a 1 President of the firm of Schmieg, Hungate & Kotzian, Inc., designers and cabinet makers, New York City. From the time of his apprenticeship (1886- 89), Mr. Schmieg has been continually engaged in the making of line furniture in Germany, Erigland, and America. He is a student of woods and one of America's foremost authbrities on furniture and cabinet making.

  • The Condensed Tannins of Okoume (Aucoumea Klaineana Pierre)
    www.nature.com/scientificreports OPEN The condensed tannins of Okoume (Aucoumea klaineana Pierre): A molecular structure and thermal stability study Starlin Péguy Engozogho Anris 1,2*, Arsène Bikoro Bi Athomo1,2, Rodrigue Safou Tchiama2,3, Francisco José Santiago-Medina4, Thomas Cabaret1, Antonio Pizzi4 & Bertrand Charrier1 In order to promote convenient strategies for the valorization of Aucoumea klaineana Pierre (Okoume) plywood and sawmill wastes industry in the felds of adhesives and composites, the total phenolic content of Okoume bark, sapwood and heartwood was measured. The molecular structure of tannins extracted from the bark was determined by Matrix Assisted Laser Desorption/Ionization Time-Of-Flight (Maldi-ToF) mass spectrometry and Fourier transform infrared spectroscopy (FTIR). The total phenolic content displayed signifcant diference (p = 0.001) between the bark, sapwood and heartwood which decreased as follows: 6 ± 0.4, 2 ± 0.8 and 0.7 ± 0.1% respectively. The pro-anthocyanidins content was also signifcantly diferent (p = 0.01) among the three wood wastes, and the bark was the richest in condensed tannins (4.2 ± 0.4%) compared to the sapwood (0.5 ± 0.1%) and heartwood (0.2 ± 0.2%). Liquid chromatography coupled mass spectroscopy (LC-MS) and Maldi-ToF analysis of the bark showed for the frst time that Okoume condensed tannins are fsetinidin, gallocatechin and trihydroxyfavan based monomers and complex polymers obtained with glycosylated units. No free catechin or robitinidin units were detected, whereas distinctive dihydroxy or trihydroxyfavan-3-benzoate dimers were observed in the investigated condensed tannin extracts. FTIR analysis showed the occurrence of glucan- and mannan-like sugars in the condensed tannins, and Maldi-ToF highlighted that these sugars should account for ten glycosylated units chemically bonded with two fsetinidins and one gallocatechin trimer.

Martin Cheek¹, Barthelemy Tchiengue2, Xander van der Burgt¹ ¹Science, Royal Botanic Gardens, Kew, Richmond, Surrey, U.K. 2 IRAD-Herbier National Camerounais, Yaoundé, BP 1601, Cameroon Corresponding author: Martin Cheek¹ Email address: [email protected] ABSTRACT This is the first revision in nearly 130 years of the African genus Pseudohydrosme, formerly considered endemic to Gabon. Sister to Anchomanes, Pseudohydrosme is distinct from Anchomanes because of its 2–3-locular ovary (not unilocular), peduncle concealed by cataphylls at anthesis and far shorter than the spathe (not exposed, far exceeding the spathe), stipitate fruits and viviparous (vegetatively apomictic) roots (not sessile, roots non-viviparous). Three species, one new to science, are recognised, in two sections. Although doubt has previously been cast on the value of recognising Pseudohydrosme buettneri, of Gabon, it is here accepted and maintained as a distinct species in the monotypic section, Zyganthera. However, it is considered to be probably globally extinct. Pseudohydrosme gabunensis, type species of the genus, also Gabonese, is maintained in Sect. Pseudohydrosme together with Pseudohydrosme ebo sp.nov. of the Ebo Forest, Littoral, Cameroon, the first addition to the genus since the nineteenth century, and which extends the range of the genus 450 km north from Gabon, into the Cross-Sanaga biogeographic area.

  • An Expanded Nuclear Phylogenomic PCR Toolkit for Sapindales1
    Applications in Plant Sciences 2016 4(12): 1600078 Applications in Plant Sciences PRIMER NOTE AN EXPANDED NUCLEAR PHYLOGENOMIC PCR TOOLKIT FOR SAPINDALES1 ELIZABETH S. COLLIns2,4, MORGAN R. GOSTEL3, AND ANDREA WEEKS2 2George Mason University, 4400 University Drive, MSN 3E1, Fairfax, Virginia 22030-4444 USA; and 3Department of Botany, National Museum of Natural History, Smithsonian Institution, MRC 166, P.O. Box 37012, Washington, D.C. 20013-7012 USA • Premise of the study: We tested PCR amplification of 91 low-copy nuclear gene loci in taxa from Sapindales using primers developed for Bursera simaruba (Burseraceae). • Methods and Results: Cross-amplification of these markers among 10 taxa tested was related to their phylogenetic distance from B. simaruba. On average, each Sapindalean taxon yielded product for 53 gene regions (range: 16–90). Arabidopsis thaliana (Brassicales), by contrast, yielded product for two. Single representatives of Anacardiaceae and Rutacaeae yielded 34 and 26 products, respectively. Twenty-six primer pairs worked for all Burseraceae species tested if highly divergent Aucoumea klaineana is excluded, and eight of these amplified product in every Sapindalean taxon. • Conclusions: Our study demonstrates that customized primers for Bursera can amplify product in a range of Sapindalean taxa. This collection of primer pairs, therefore, is a valuable addition to the toolkit for nuclear phylogenomic analyses of Sapindales and warrants further investigation. Key words: Anacardiaceae; Burseraceae; low-copy nuclear genes; microfluidic PCR; Rutaceae. Low-copy nuclear gene regions offer increased phyloge- PCR-based target enrichment, a method that allows simultane- netic utility for species- and population-level studies of plants ous and cost-effective amplification of multiple loci (Blow, as compared to chloroplast and nuclear ribosomal markers 2009; Uribe-Convers et al., 2016).

E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al.

  • Brown Root Rot Disease in American Samoa's Tropical Rain Forestsl
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by ScholarSpace at University of Hawai'i at Manoa Brown Root Rot Disease in American Samoa's Tropical Rain Forestsl Fred E. Brooks 2 Abstract: Phellinus noxius (Corner) Cunningham causes root and lower stem rot of woody plants throughout the South Pacific region. Its hosts include rubber, mahogany, cacao, and many timber, fruit, and landscape trees. Though endemic to the Tropics, no reports were found describing brown root rot disease in na­ tive forests, exclusively. Incidence, distribution, and host range of P. noxius were measured in primary and secondary rain forests on Tutuila Island, American Samoa. Phellinus noxius was recorded in 19 of 20 strip transects and 1.2-ha es­ tablished plots and in all vegetation types, infecting 37 tree species in 30 genera and 22 families. Species most affected were Myristica Jatua, Dysoxylum samoense, and Hibiscus tiliaceus-25, 16, and 10%, respectively. Of 62 infection centers, 33 contained the same tree species and 13 were dominated by a single species. The fewest infections were recorded at primary montane and ridge top sites. Regenerating secondary valley sites had the highest incidence of disease and greatest number of infection centers. Infection centers at these disturbed sites also contained more trees on average than centers at primary sites. Disease in­ cidence was influenced more by human disturbance than by vegetation type, topography, stem diameter, stem density, or soil type. The disturbed sites also appeared to lack the species richness of mature sites. This agrees with other host/pathogen associations, such as Douglas-fir/P.
